Scholarcy highlights

  • Chlorophenols are extensively used chemicals in daily life and their amounts present in wastewater are considerable
  • Compared with GR/TiO2, the addition of HPW accelerated the separation of the photo generated electron-hole pairs as well as enhanced the photocatalytic activity owing to the generation of a large number of OH and O2− in the reactions
  • There was no significant difference in the contribution of ROS to the photocatalytic degradation for PCP
  • This review provides an in-depth and critical analysis of the recently developed strategies to countermeasure the limitations and improve the overall performance of photocatalytic technology for the remediation of treated palm oil mill effluent with respect to the preparation of visible light active photocatalyst, strategies to eliminate the need for the recovery of photocatalyst, and parametric optimization of the photocatalytic process
  • Our results indicated that eggs incubated at low temperature had earlier detection of heartbeat, longer incubation length, lower growth rate post-hatch, and higher post-hatch mortality, compared to eggs incubated under intermediate temperatures
  • Higher than 80% of ciprofloxacin is degraded in the pH range from 5 to 8, and the highest degradation percent is achieved at pH 8
  • Mixture toxicity was modelled by concentration addition and independent action, in combination with different expressions of exposure: three equilibrium-based doses of metal ions bound to the biotic ligands) and one kinetically controlled dose metrics
